If you put five football fields together you would have the approximate size of the gaming floor at the Galaxy Casino in Macau China. It felt like I walked a mile just to cover the length of one side of the casino. And it was full in every position almost the entire way. The only larger casino I have ever visited is Genting in Malaysia which housed 11 separately themed hotel and casinos technically under one roof – one million plus square feet of gaming if my memory is correct. Below is a video of the lobby fountain feature at the Galaxy Hotel Casino.
